I used to do this all the time a long time ago, and I experience the same things as you guys do.
Not to go off topic, but since this is kinda strange - and kind of hard to explain..
I can still to this day focus on the inside of myself, and make some sort of energy inside of me flow to my hands, hell I was just doing it last night and it feels great except I was focusing it towards my chest and back.
Its like.. I just call energy up from the back of my spine ( thats where it feels like it comes from) by ..flexing my brain?

I just made it flow to both legs.
